An international research team has discovered the first example of a supernova, known as SN 2018ivc, showing an unprecedented rebrightening at millimeter wavelengths about one year after the explosion. With the help of the Atacama Large Millimeter/submillimeter Array -- or ALMA -- the analysis revealed that the dying massive star ejected a large amount of its envelope due to a strong binary interaction with a companion star that took place about 1500 years before the explosion. In a paper published in The Astrophysical Journal Letters, the team posits that this rebrightening event in SN 2018ivc provides a missing link between supernovae -- or SN -- that occur in binary star systems and those that involve solitary massive stars.

Researchers at Tohoku University have analyzed samples from asteroid Ryugu. They identified some of the oldest solids from the solar system to date, and their findings suggest that the asteroid initially formed in the outer reaches of the solar system.

Osaka Metropolitan University scientists identified about 140,000 molecular clouds in the Milky Way Galaxy from large-scale data of carbon monoxide molecules, observed in detail by the Nobeyama 45-m radio telescope. Using artificial intelligence, the researchers estimated the distance of each of these molecular clouds to determine their size and mass, successfully mapping the distribution of the molecular clouds in the Galaxy in the most detailed manner to date.

When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using light polarization, a research group has found a workaround for this, enabling astronomers to calculate the hidden energy of gamma-ray bursts.

Magnetic nozzle plasma thrusters are thought of as the future of space travel. But one problem has hampered their development – plasma detachment. A recent study has shown that spontaneously excited plasma waves help magnetic nozzles overcome the plasma detachment problem, a rare instance of plasma instabilities having a positive effect on engineering.

Studying an atomic clock on-board a spacecraft inside the orbit of Mercury and very near to the Sun could be the trick to uncovering the nature of dark matter.

Muon non-destructive analysis of Asteroid Ryugu revealed the raw materials of solid matter at the outer regions of the early solar system. The samples contain less oxygen relative to silicon than typical CI chondrites, indicating that previous CI chondrite samples may have been contaminated by terrestrial materials, thus redefining the standard elemental composition of solid materials in the solar system.

The international collaboration developing the Prime Focus Spectrograph (PFS), which includes Kavli IPMU and more than 20 collaborating institutions, has marked a significant testing milestone by successfully taking spectra of targeted stars.

Space missions already use electric propulsion devices, where electromagnetic fields are utilized to generate the thrust of spacecraft. One such electrodeless device, which harnesses radio frequency (rf) to generate plasma and a magnetic nozzle (MN) to channel and accelerate plasma, has shown immense promise in pushing the boundaries of space travel. But scientists have so far failed to achieve efficient conversion of the rf power to thrust energy. Now, a Tohoku University researcher has achieved a 30% conversion efficiency, the biggest rate to date.

Only satellites were watching when the world's fourth-largest proglacial lake suddenly drained in 2020. Hokkaido University researchers now uncovered the event and analysed the cause—the collapse of a sediment bump at the outlet of the lake.

Supermassive black holes can launch fast-moving plasma, which emit strong radio signals known as radio jets. Despite being discovered over 40 years ago, much remains unknown about how radio jets are produced. Now, a research team, led by Tohoku University astrophysicists, has attempted to clarify how plasma gets loaded into radio jets.

A team of researchers have analyzed the elemental composition of asteroid Ryugu using an artificially generated muon beam from a particle accelerator.

Researchers have used giant lobes of gamma radiation to find that a small satellite galaxy of the Milky Way filled with dark matter, but whose emissions are more likely the result of millisecond pulsars blasting out cosmic particles.

Researchers at Osaka Metropolitan University have observed "baby stars" in the Small Magellanic Cloud, having an environment similar to the early universe. Toward one of the baby stars, they found molecular outflow, which has similar properties to those seen in the Milky Way galaxy, giving a new perspective on the birth of stars.
